Relative Contrast Sensitivity for Color Break-Up Evaluation in Field-Sequential-Color LCDs
A single-valued index, relative contrast sensitivity (RCS), was developed to quantitatively evaluate color break-up (CBU) phenomenon. The sensibility of CBU fringe was hypothesized to strongly correlate with RCS, which was defined as the integrated difference of the opponent-color signals filtered b...

| description | A single-valued index, relative contrast sensitivity (RCS), was developed to quantitatively evaluate color break-up (CBU) phenomenon. The sensibility of CBU fringe was hypothesized to strongly correlate with RCS, which was defined as the integrated difference of the opponent-color signals filtered by spatial contrast sensitivity functions. Psychometric experiments, based on methods of category scaling and adjustment respectively, were conducted to examine the proposed numerical metric. The results showed that the maximal correlation coefficient was as high as 98.9% between the subjective judgments and the computed numerical values of current experimental results. A useful application of RCS index was demonstrated by the evaluation of four driving schemes for CBU suppression. |
